Illuminating badge for a vehicle

Abstract

A badge mounted on a vehicle is provided herein. The badge includes a substrate and a housing attached thereto defining a cavity therebetween. A light source is configured to emit an excitation light. A first photoluminescent structure and a second photoluminescent structure are disposed within the badge and each is configured to convert the excitation light emitted from the light source into a converted light of a different wavelength. A light scattering layer is disposed between the first and second photoluminescent structures.

What is claimed is: 
     
       1. A badge for a vehicle, comprising:
 a substrate and a housing attached thereto defining a cavity therebetween; 
 first and second light sources disposed within the cavity and configured to emit an excitation light; 
 a first photoluminescent structure disposed between the light source and a viewable portion and separated from the light source by a gap, the gap having a varied thickness; 
 a second photoluminescent structure disposed between the first photoluminescent structure and the viewable portion and extending to a position rearwardly of the light source, wherein the first and second photoluminescent structures are configured to convert the excitation light into a converted light of a different wavelength; and 
 a light scattering layer having a varied thickness and disposed between the first and second photoluminescent structures, a maximum thickness of the light scattering layer disposed between the first and second light sources. 
 
     
     
       2. The badge for a vehicle of  claim 1 , wherein the light source is operably coupled with a circuit board, the circuit board disposed within the cavity and having a solder mask on an internal surface of the circuit board. 
     
     
       3. The badge for a vehicle of  claim 2 , wherein the first photoluminescent structure and the second photoluminescent structure each include at least one photoluminescent material therein configured to down convert an excitation light received from at least a portion of the light sources into a visible converted light. 
     
     
       4. The badge for a vehicle of  claim 1 , further comprising:
 a translucent metallic layer disposed between the second photoluminescent structure and the housing. 
 
     
     
       5. The badge for a vehicle of  claim 1 , wherein the light source is configured to emit the excitation light at a plurality of independent wavelength ranges, wherein the first photoluminescent structure is excited by a first wavelength range and the second photoluminescent structure is excited by a second wavelength range such that the first and second photoluminescent structures may be independently excited based on the independent wavelength range emitted from the light source.
